AMC was hired to prepared the 80 year old Bowfin submarine to be towed from the Pacific Fleet Submarine Museum at Pearl Harbor to Pacific Shipyards International.
The USS Bowfin has an incredible history and importance in protecting the Safety and Freedom of our great Country. AMC was honored to play an integral part in maintaining these historical submarine and the US Navy.
Sailboat Christiana broke free of her mooring offshore Honolulu Harbor and drifted into the jetty at the Harbor entrance at sunset.
Fuel and oil was seen leaking from the vessel which poised a critical risk to the navigation as the only point of entry to Honolulu Harbor for freighters, cruise ships, and rescue vessels.
Harbors Divisions of Hawaii Department of Transportation (HDOT) hired AMC to provide emergency response services in order to safely remove the vessel blocking vessel traffic while minimize the hazards to the environment.
Divers were deployed immediately at night to located the vessel and rig it for lifting and removal out of the channel.
Pacific Environmental Corporation (PENCO) was brought in to remove all the hazardous material. This was a successful critical project completed under pressure to get the Harbor operational again.
See article in the photo gallery below discussing the project in the local Honolulu news.
AMC is working on a Naval Facilities Engineering Command (NAVFAC) project in Pearl Harbor, Oahu, Hawaii. The project involves constructing a new boat ramp and finger pier to help meet the expanding needs of the U.S. Navy Seal teams stationed on Joint Base Pearl Harbor Hickam.
AMC will utilize a Watson hydraulic drill rig, its derrick barge AMC 160, and a D36 diesel hammer to pre-drill and drive new concrete piles to support a new boat ramp and finger pier.
After pile driving, the derrick barge AMC 160, in conjunction with AMC’s ADCI certified divers, will install underwater precast concrete pile caps, suspended slabs, and boat ramp panels.
The U.S. Army Corps of Engineers contracted AMC to conduct maintenance dredging in Port Allen, Kauai, Hawaii.
AMC dredged approximately 482,000 cubic yards over 90 days. The crews were working in two 12 hour shifts, seven days a week which resulted in the project being complete well in advance of the projected schedule.
Our Team’s knowledge of the local environment played a critical role in the success of this project.
AMC towed a version of The Ocean Cleanup’s prototype from the Pacific Garbage patch to our office in Honolulu. AMC utilized its Tug and barge fleet to assist with making modifications and structural reinforcements for the system to better withstand the harsh environment of the Pacific Ocean.
The AMC team made a fast turnaround to ensure the system was deployed and operational with minimal downtime. Our team is extremely proud to have played a role in protecting our Oceans and making them a cleaner and better place for future generations. Mahalo!
AMC is working as a sub-contractor to Kiewit Infrastructure West Co. to pump more than 20,000 CY of sand from offshore of Waikiki Beach to a dewatering basin where Kiewit then distributed the sand on Waikiki Beach.
AMC utilized a newly purchased Damen hydraulically driven dredge pump connected to an excavator with an AMC-designed jib.
Our team was able to beat production and finished another incident-free project.
The American Shore and Beach Preservation Association(ASBPA )honored AMC with a National Award for the Best Restored Beach for this project.
AMC is placing activated carbon (AC) on the seafloor under numerous piers and in open water areas of Pearl Harbor to encapsulate contaminates. Before any work was completed, AMC needed to create a layout specifically for each area under the pier and open water area to ensure project requirements of 2” and 1” application thicknesses.
AMC uses a unique approach to disburse AC which utilizes a blower machine placed on the barge and loaded via telehandler forklift into the blower’s hopper (2,500 lbs of AC). Deck crew then distributes AC under the pier into the desired square footage.
In open water application, AMC devised a floating target box using HDPE piping and attached turbidity curtains to create a movable containment area while the crew applied the product. So far date the project has applied roughly 3.9 million pounds of AC onto the ocean floor.
This project consisted of repairing several existing leaks and an undermined section of the 48” Hilo WWTP outfall pipeline, at an approximate 50’ depth. The leak repair portion of this work consisted of several methodologies, including the use of oakum, epoxy grout, large stainless steel pipe clamps, and grout jackets. Repairing the undermined portion of the outfall pipe required excavation, placement of filter fabric, and the placement and pouring of several layers of concrete fabric form bags and mats. The final design of the fabric forms and the concrete mix design were completed by AMC. AMC utilized specialized charter vessels and concrete mixing and pumping equipment to set up an offshore batch plant, and pump concrete to a depth of 50’. AMC was able to overcome challenges with concrete material logistics, bad weather, and stringent BMP requirements to complete the project.
